在做操作之前需要手工备份OCR，这样即使修改失败，也能还原回来

对IP 地址做如下修改：

192.168.72.30 rac1 ----->192.168.72.70

192.168.72.40 rac2 ----->192.168.72.80

192.168.72.31 rac1-vip ------>192.168.72.71

192.168.72.41 rac2-vip ------>192.168.72.81

10.10.10.30 rac1-priv ------>11.11.11.70

10.10.10.40 rac2-priv ------->11.11.11.80

一．停止oracle相关的所有进程, 包括数据库, asm, node application, crs本身.

1.1 查看当前系统上crs运行的状态

[root@rac1 oracle]# crs_stat -t

Name Type Target State Host

------------------------------------------------------------

ora....SM1.asm application ONLINE ONLINE rac1

ora....C1.lsnr application ONLINE ONLINE rac1

ora.rac1.gsd application ONLINE ONLINE rac1

ora.rac1.ons application ONLINE ONLINE rac1

ora.rac1.vip application ONLINE ONLINE rac1

ora....SM2.asm application ONLINE ONLINE rac2

ora....C2.lsnr application ONLINE ONLINE rac2

ora.rac2.gsd application ONLINE ONLINE rac2

ora.rac2.ons application ONLINE ONLINE rac2

ora.rac2.vip application ONLINE ONLINE rac2

1.2 关闭数据库

　　[root@raw1 bin]# ./srvctl stop database -d raw

1.3 关闭asm实例

[root@rac1 oracle]# srvctl stop asm -n rac1

[root@rac1 oracle]# srvctl stop asm -n rac2

1.4 关闭其他应用程序

[root@rac1 oracle]# srvctl stop nodeapps -n rac1

[root@rac1 oracle]# srvctl stop nodeapps -n rac2

1.5 关闭crs后台进程, 在操作系统一级中止运行的crs后台进程, 必须在所有节点上运行.

一节点：

[root@rac1 oracle]# /etc/init.d/init.crs stop

Shutting down Oracle Cluster Ready Services (CRS):

Sep 22 11:14:22.759 | INF | daemon shutting down

Stopping resources. This could take several minutes.

Successfully stopped CRS resources.

Stopping CSSD.

Shutting down CSS daemon.

Shutdown request successfully issued.

Shutdown has begun. The daemons should exit soon.

二节点：

[root@rac2 oracle]# /etc/init.d/init.crs stop

Shutting down Oracle Cluster Ready Services (CRS):

Sep 22 11:15:00.995 | INF | daemon shutting down

Stopping resources. This could take several minutes.

Successfully stopped CRS resources.

Stopping CSSD.

Shutting down CSS daemon.

Shutdown request successfully issued.

Shutdown has begun. The daemons should exit soon.

二修改操作系统的ip设置

2.1 修改 /etc/hosts 文件。保持2个节点的一致

[root@rac1 oracle]# cat /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost.localdomain localhost

192.168.72.70 rac1

192.168.72.80 rac2

192.168.72.71 rac1-vip

192.168.72.81 rac2-vip

11.11.11.70 rac1-priv

11.11.11.80 rac2-priv

2.2 在两个节点上分别修改eth0和eth1地址：

一节点eth0：

[root@rac1 oracle]# more /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=none

BROADCAST=192.168.72.255

HWADDR=00:0C:29:C8:3D:94

IPADDR=192.168.72.70

NETMASK=255.255.255.0

NETWORK=192.168.72.0

ONBOOT=yes

TYPE=Ethernet

USERCTL=no

IPV6INIT=no

PEERDNS=yes

二节点eth0：

[root@rac2 oracle]# more /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=none

BROADCAST=192.168.72.255

HWADDR=00:0c:29:37:d0:3a

IPADDR=192.168.72.80

NETMASK=255.255.255.0

NETWORK=192.168.72.0

ONBOOT=yes

TYPE=Ethernet

USERCTL=no

IPV6INIT=no

PEERDNS=yes

一节点eth1：

[root@rac1 oracle]# more /etc/sysconfig/network-scripts/ifcfg-eth1

# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]

DEVICE=eth1

ONBOOT=yes

BOOTPROTO=none

IPADDR=11.11.11.70

NETMASK=255.0.0.0

HWADDR=00:0C:29:C8:3D:9E

USERCTL=no

IPV6INIT=no

PEERDNS=yes

TYPE=Ethernet

二节点eth1：

[root@rac2 oracle]# more /etc/sysconfig/network-scripts/ifcfg-eth1

# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]

DEVICE=eth1

ONBOOT=yes

BOOTPROTO=none

IPADDR=11.11.11.80

NETMASK=255.0.0.0

HWADDR=00:0c:29:37:d0:44

TYPE=Ethernet

USERCTL=no

IPV6INIT=no

PEERDNS=yes

2.3 在两个节点上分别重启网络服务，使修改的IP生效。

[root@rac1 ~]# service network restart

[root@rac2 ~]# service network restart

三．启动crs, 设置oracle中ip地址相关的设置.

　　3.1 在两个节点启动crs, 并关闭随crs启动的应用程序

[root@rac1 ~]# /etc/init.d/init.crs start

Startup will be queued to init within 30 seconds.

[root@rac2 ~]# /etc/init.d/init.crs start

Startup will be queued to init within 30 seconds.

由于oracle所有应用设置为自动启动, 所以在crs启动时会试图启动所有的服务, 但是在对oracle相关的ip地址进行设置时需要crs处于运行状态. 但是数据库, asm和node application处于停止状态, 在一个节点执行以下命令：

[root@rac1 admin]# ./srvctl stop database -d orcl

[root@rac1 admin]# srvctl stop asm -n rac1

[root@rac1 admin]# srvctl stop asm -n rac2

[root@rac1 admin]# srvctl stop nodeapps -n rac1

[root@rac1 admin]# srvctl stop nodeapps -n rac2

[root@rac1 admin]# crs_stat -t

Name Type Target State Host

------------------------------------------------------------

ora....SM1.asm application OFFLINE OFFLINE

ora....C1.lsnr application OFFLINE OFFLINE

ora.rac1.gsd application OFFLINE OFFLINE

ora.rac1.ons application OFFLINE OFFLINE

ora.rac1.vip application OFFLINE OFFLINE

ora....SM2.asm application OFFLINE OFFLINE

ora....C2.lsnr application OFFLINE OFFLINE

ora.rac2.gsd application OFFLINE OFFLINE

ora.rac2.ons application OFFLINE OFFLINE

ora.rac2.vip application OFFLINE OFFLINE

3.2 使用oifcfg修改网卡设置, oifconfig可以用来设置和查看网卡使用的方式.

注：如果修改的网段相同，可以不做这一步。

-- 查看当前配置：

[root@rac1 oracle]# oifcfg getif -global

eth0 192.168.72.0 global public

eth1 10.0.0.0 global cluster_interconnect

-- 删除当前配置

[root@rac1 oracle]# oifcfg delif -global eth0

[root@rac1 oracle]# oifcfg delif -global eth1

[root@rac1 oracle]# oifcfg getif

-- 重新添加

[root@rac1 oracle]# oifcfg setif -global eth0/192.168.72.0:public

[root@rac1 oracle]# oifcfg setif -global eth1/11.11.11.0:cluster_interconnect

[root@rac1 oracle]# oifcfg getif

eth0 10.85.10.0 global public

eth1 192.168.1.0 global cluster_interconnect

[root@rac1 oracle]# oifcfg iflist

eth0 192.168.72.0

eth1 11.0.0.0

注意：这里IP 地址最一个为0. 代表的是一个网段。修改的时候要切记。否在在启动OCR 时会报如下错误：

[ CRSOCR][4054413904] OCR context init failure. Error: PROC-44: 网络地址和网络接口操作中出错网络地址和网络接口操作错误 [7]

3.3 修改VIP

[root@rac1 oracle]# srvctl modify nodeapps -n rac1 -A 192.168.72.71/255.255.255.0/eth0

[root@rac1 oracle]# srvctl modify nodeapps -n rac2 -A 192.168.72.81/255.255.255.0/eth0

3.4 设置listener.ora和tnsnames.ora, 检查这些文件中是否有指定原来ip的地方, 修改为更改后的ip地址。

[root@rac1 admin]# more listener.ora

# listener.ora.rac1 Network Configuration File: /oracle/app/product/10.2.0/db_1/network/admi

n/listener.ora.rac1

# Generated by Oracle configuration tools.

LISTENER_RAC1 =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip)(PORT = 1521)(IP = FIRST))

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.72.70)(PORT = 1521)(IP = FIRST))

)

SID_LIST_LISTENER_RAC1 =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /oracle/app/product/10.2.0/db_1)

(PROGRAM = extproc)

)

注意：如果你使用了ocfs，修改ocfs配置文件(/etc/ocfs/cluster.conf),验证修改后是否可用。

3.5 启动node applications, asm, 数据库

[root@rac1 admin]# srvctl start nodeapps -n rac1

[root@rac1 admin]# srvctl start asm -n rac1

[root@rac1 admin]# srvctl start nodeapps -n rac2

[root@rac1 admin]# srvctl start asm -n rac2

[root@rac1 admin]# crs_stat -t

Name Type Target State Host

------------------------------------------------------------

ora....SM1.asm application ONLINE ONLINE rac1

ora....C1.lsnr application ONLINE ONLINE rac1

ora.rac1.gsd application ONLINE ONLINE rac1

ora.rac1.ons application ONLINE ONLINE rac1

ora.rac1.vip application ONLINE ONLINE rac1

ora....SM2.asm application ONLINE ONLINE rac2

ora....C2.lsnr application ONLINE ONLINE rac2

ora.rac2.gsd application ONLINE ONLINE rac2

ora.rac2.ons application ONLINE ONLINE rac2

ora.rac2.vip application ONLINE ONLINE rac2

3.6 确认IP, 修改完成。
